Question

(-2xraised to5 y square)2hole to power7​

Answer 1

Answer:

Step-by-step explanation:

(ab)n = anbn

"Raise each factor to that same power."

For example,  (ab)3 = a3b3.

Why may we do that?  Again, according to what the symbols mean:

(ab)3 = ab· ab· ab = aaabbb = a3b3.

The order of the factors does not matter:

ab· ab· ab = aaabbb.

Problem 5.   Apply the rules of exponents.

  a)   (xy)4 = x4y4   b)   (pqr)5 = p5q5r5   c)   (2abc)3 = 23a3b3c3

 d)   x3y2z4(xyz)5 = x3y2z4· x5y5z5   Rule 2,

 

 = x8y7z9   Rule 1.
